Abstract: 1338547 17#-(Tetrahydropyran-4-yloxy) steroids SYNTEX CORP 5 April 1972 [20 April 1971 3 Feb 1972] 15774/72 Heading C2U Novel steroids of the formulae wherein R<SP>1</SP> is H or CH 3 ; R<SP>2</SP> is H, CH 3  or C 2 H 5 ; R<SP>3</SP> is H or α- or #-CH 3 ; R<SP>4</SP> is =CHOH, H 2  or H(α-CH 3 ); and R<SP>6</SP> is H, C 1-8  alkyl or aryl are prepared from the coresponding 17#-ols and 4- halotetrahydropyrans. Alternatively an appropriate 3-keto-#<SP>4</SP>-17#-ol may be treated with 4- methoxy-5,6-dihydro-2H-pyran in the presence of an acid to give the corresponding 17#-(4- methoxy-tetrahydropyran-4-yl-oxy) compound, this then treated with an acid anhydride or acid chloride in the presence of sodium methoxide in dimethyl sulphoxide, the resulting 3-acyloxy- #<SP>3,5</SP>-compound reduced to the corresponding #<SP>5</SP>-3#-ol, this treated with LiAlH 4  and AlCl 3  to give the corresponding 3#-hydroxy-17#-(tetrahydropyran-4-yloxy)-#<SP>5</SP>-compound and this oxidized to the #<SP>4</SP>-3-one which may then be reduced under Birch conditions to the corresponding 5α-H compound, which can also be obtained by catalytic hydrogenation of the #<SP>5</SP>- 3#-ol and oxidation of the 5α-H-3#-ol thus produced. In variants of this process the treatment with the 4-methoxy-5,6-dihydro-2H- pyran and subsequent treatment with LiAlH 4  and AlCl 3  can be effected on a 3#-acyloxy-#<SP>5</SP>-17#- ol, with subsequent oxidation of the 17#- (tetrahydropyran-4-yloxy)-#<SP>5</SP>-3#-ol produced to the corresponding #<SP>4</SP>-3-one, or on a 3#- acyloxy-5α-H-17#-ol with intermediate hydrolysis of the 3#-acyloxy-17#-(4-methoxytetrahydropyran-4-yloxy)-5α-H compound to the 3#-ol and final oxidation of the 17#-(tetrahydropyran-4-yloxy)-5α-H-3#-ol to the corresponding 3-one. The last-named product may subsequently be treated with ethyl formate in a base to give the corresponding 2-hydroxymethylene compound which on hydrogenation gives the corresponding 2α-methyl compound. In the ring A aromatic series either of the above methods may be used to introduce the 17#- (tetrahydropyran-4-yloxy) grouping, and any resulting 3-acylate may be hydrolysed to the corresponding 3-ol which may then be reesterified. 3#-Acetoxy-5α-androstan-17#-ol is prepared by NaBH 4  reduction of 3#-acetoxy-5α-androstan- 17-one, prepared in turn by catalytic hydrogenation of 3#-acetoxyandrost-5-en-17-one. 3-Acetoxy-estra-1,3,5(10)-trien-17#-ol is prepared by reduction of 3-acetoxy-estra-1,3,5(10)- trien-17-one, in turn prepared by acylation of estra-1,3,5(10)-trien-3-ol-17-one. Similarly prepared are 3-acetoxy-18-methylestra-1,3,5(10)-trien 17#-ol and 3-acetoxy-18-ethylestra-1,3,5(10)-trien- 17#-ol. The novel steroids are stated variously to possess anabolic, androgenic, estrogenic and anti fertility activity, and they may be made up into pharmaceutical compositions with suitable carriers.

Abstract: 697,557. Friction clutches. BAD IN, F. Julr 4, 1951 [July 5, 1950; Feb. 6, 1951. ; March 23, 1951], No. 15884/51. Class 80 (ii). A centrifugal powder coupling comprises a rotatable casing 23 containing a quantity of powder and enclosing a rotor 22, having on at least two annular surfaces a plurality of regularly spaced grooves 26 or the like, and protrusions 27 between the grooves on at least one of the surfaces, to provide a series of restricted spaces in which during operation powder may accumulate to provide a driving connection between the rotor and casing, the grooves 26 ex-. tending substantially radially of the rotor and each having at least one of its edges located in or inclined to a plane perpendicular to the axis of the rotor, so as to form inclined surfaces serving to guide the powder into said restricted spaces and to disperse powder therefrom when the coupling is to be uncoupled. As shown, the grooves 26 are shaped as segments of a circle and holes 28 allow the powder to pass from side to side of the rotor. In one modification, Figs. 3, 4 (not shown), grooves are directed in the radial plane on the sides of the disc and additional axially directed grooves are provided on the periphery of the disc. In another modification, Figs. 6-9 (not shown), the rotor is comprised by a corrugated disc having radially directed serrations, each serration forming a groove at one side of the rotor and a protrusion at the other, the sides of the grooves either being equally inclined to the radial plane or alternatively one side having a steep incline and the other a shallow incline. In yet another modification, Fig. 10 (not shown), the protrusions are formed by teeth having tops inclined in the peripheral direction and inclined flanks, triangular shaped spaces between adjacent teeth formed by the inclined flanks constituting radially directed grooves. The surfaces of the rotor and casing may be roughened, e.g., by the Schoop process.

Title: Improvements in or relating to train describing equipment
IPC: B61L25/04
Filed: 1938-05-27
Abstract: 517,766. Railway signalling apparatus. STANDARD TELEPHONES & CABLES, Ltd., GRIFFITHS, J. B., and BROWN, A. May 27, 1938, No. 15930. [Class 105] The position and description of a train while in various sections of a length of track which may include passage on to a parallel track is given by the selection of a particular display position within a series of display positions to denote the position of the train on the track and by the selection of a particular series (or a combination) from a group of such series to denote the train description. For instance with the track arrangement shown in Fig. 1, an express passenger train moving on the slow line has its position and description given on a panel, Fig. 2, by the illumination of a square EP appropriate to the position of the train, e.g., approaching Box A, in a column appropriate to the train description, namely express passenger. If the train passes on to the fast line the description is transferred to the fast line panel. The description sent by code from the signal box A energizes at signal box B a particular relay SG, FG. EP, or OP, according as the description is slow goods, fast goods, express passenger, or ordinary passenger. Assuming that the relay EP is energized it gives the indication " express passenger approaching box A." When the train enters track section 201T, the indication is'transferred to the next square in the'same column, so denoting "express passenger approaching signal 1/3." This is effected by a relay 1/3 EP being energized over a back contact 201t of the track relay and a front contact ep<2> of the relay EP. The indication " approaching box A" is extinguished as soon as the relay 1/3 EP is energized, since a contact 1/3 eP<3> thereof energizes a relay 1/3B which opens its back contact 1/3b1 to drop the relay EP. Similar transfer and cancellation actions arise as the train proceeds. If the train passes on to the fast line by the points 1001 being put at reverse the description is transferred to the fast line panel. The action is that, as the train enters track section 205T with the points at reverse, a relay 5BB, is energized over a back contact 205t of the track relay and a reverse contact R of a points indicator relay 101 wkr and thereupon a circuit is closed from + ve through a relay 1/3 AB, a front contact 5 bb 3 of the relay 5BB, a front contact 1/3 ep reverse contact R of a points indicator relay 1001 wkr and thereupon a circuit is closed from + ve through a relay 1/3 AB, a front contact 5 bb 3 of the relay 5BB; a front contact 1/3 ep 4 of the relay 1/3 EP and line c, to relay 4/6 EP, not shown. The relay 4/6 EP then gives, on the fast line panel, the indication express passenger approaching signal 4/6. The indication on the slow line panel is extinguished by the relay 1/3 EP being dropped when a back contact 1/3 ab 1 of the relay 1/3 AB is opened. Specification 366,919, [Group XXXVIII], is referred to.

Abstract: 378,132. Turbine plant. NICHOLSON, A. 1., 60, Newton Street, Greenock, Renfrewshire. June 2, 1931, No. 16051. [Class 110 (iii).] Relates to auxiliary dynamos normally driven from the main engines of a large power plant, such as a ship's engines, but provided with an auxiliary motor by which they can be driven in case of need and consists in bringing the auxiliary motor into action by means operated by the pressure or torque obtaining in it or in the shafts 'or gearing whereby the main shaft drive is transmitted to it. In the arrangement shown in Fig. 1 the turbine B drives the dynamo K through the shafts A, E, clutch C, D and gearing H, J. On the shaft E is an auxiliary turbine F provided with a governor G so adjusted that when the turbine B is revolving at its normal speed steam is cut off from the turbine F. As the speed drops the valve N, Fig. 2, admits steam to the turbine and to the piston R, by which a catch Q is released and the clutch C, D is disengaged by the lever O and spring P, To admit of re-engaging the clutch when the turbine B recovers speed the load in the governor G is increased by means of a lever L until the turbine F is running at the same speed as the turbine B. That this equality may be ascertainable a neon lamp T is flashed once in every revolution of the shaft E by a magneto E ; when the two shafts are rotating in synchron. ism a disc U driven from the shaft A appears stationary. The device is also applicable to reciprocating engines. In the arrangement shown in Fig. 4 the dynamo 14 is connected to the auxiliary motor 13 by a free-wheel clutch 11 and to the main motor by helical gearing 15, 16 of a clutch 12. When the clutch 11 picks up in consequence of the slowing down of the main motor the end thrust produced by the gearing 15, 16 is reversed and actuates gearing to release the clutch 12.
